Currently, I have an undergravel filter. I'm over the maintenance, and feel like I just can't do a good enough job keeping the tank/gravel free from debris.
Currently - Java Moss, Java Fern, Anubias (will be slowly adding more plants over time)
Size - I think it's 3.5gallons. I put the dimensions into different calculators online, and I get different numbers
The lowest I get is 3.5, highest is 4.3 so I'm going with 3.5g
Air Pump - Profile 1000 (have no idea what this means..)
I was thinking initially sponge filter. Since I already have an air pump and the tubing. But then I heard they aren't good for plants. I was planning on getting one of those valve things too, to help adjust the flow, in case it's too strong.
Now I'm thinking maybe some sort of internal filter that I can hook onto the inside of the tank. I'm concerned how much room the sponge filter will take. I'd love to keep as much floor space as possible for more plants. I'm also unclear how these internal filters work..will there be a intake sucking up water that I may need to baffle? How easy is set up? Is it like buying a sponge filter..meaning, does it not come with everything I need to get it going?
I can't use a HOB filter. The hood is too much in the way, and it'll be a pain.
So: sponge or internal?
-I want something that will do it's job
-easier maintenance than UGF
-After MANY battles trying to baffle my current UGF, I want a LOW flow and if it does need to be baffled it needs to be able to be done so easy and cheap
-Suitable for my plants
Soooo if you had my set up, what would you go for? Or am I missing a better filter that I should be using? I'm super inexperienced and have been researching this for days and I'm going in circles!!
